stairs disappearin 3d at 90 degree bend

Why have the stairs disappeared in the 3D view, even though they’re shown on the floor plan? Also, in the 3D view, the reference lines seem to extend all the way to the floor slab. Is this because there’s only one step at that bend? I don’t think it’s a problem, even if there’s only one.

Is this due to a bug or a rule associated with (Ctrl+T)? Thank you all.

Hi @horewa

This appears to be the default behavior for stairs without Finish. You can also see the difference when you select "end with tread" or "end with riser".

Thank you for your reply, Ricardo Lopez. Goodness, you’re so quick! I hope I haven’t disturbed your downtime, but I’m not too keen on the result shown in the image. I reckon people might ask me, ‘Is it safe to walk on?’ Is there a way to ensure the concrete steps extend right down to the floor slab, rather than just the finish? Thank you

I’m sorry, Ricardo Lopez; I don’t mean to show you any disrespect or try to test you or anything like that—not at all—but I’ve accidentally stumbled upon what might be a solution, so here’s the thing

I changed what was originally "vertical cut" to "vertical + horizontal cut" and it immediately turned out like this

tadaaa...

All right, Ricardo Lopez, I’ll definitely give it a go
